Count down from 10 with the red-bottomed dragons and do your 'sums with bums' in this hilarious storybook for preschoolers, which is a twist on the classic nursery rhyme Ten Green Bottles.

Join the excitable little dragons in the castle as they chomp, chew, learn to breathe fire and fly, causing all kinds of mischief and mayhem.

Packed full of silly humour and with lots to spot in busy scenes, this riotous rhyming story by Barry Timms and Mike Byrne is perfect for reading aloud and sharing together. With a surprise gatefold ending, a number line to count up to 10 and back down again plus a page of simple adding up, first maths skills have never been so much fun!
